Description

Technical Field

[0001] The invention relates to a wire end processing device, in particular to a wire end processing device used on a wire taking-up machine. Background Art

[0002] The wire take-up machine is a device that winds the wire harness onto a bobbin. The wire take-up machine generally includes a rotating disk, which is driven by a wire take-up power device. The wire harness is unwound and passed through a transition wheel and then wound onto the bobbin through a wire arrangement mechanism. When taking up the wire, the bobbin is placed on the rotating disk of the wire take-up machine, and then the power is transmitted between the bobbin and the rotating disk through the block and the groove. The wire ends of the wire harness need to be wound around the wire end clamp of the rotating disk so that the wire harness can be completely wound around the bobbin. After the bobbin is full of wire harness, the wire end clamp needs to be opened and the wire ends need to be taken out so that the full bobbin can be removed. However, the removal of wire ends is currently done manually, so one machine needs to cooperate with one operator, which increases labor costs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a thread end processing device for a wire take-up machine, which can automatically open a thread end clamp to remove the thread end, thereby replacing manual labor and reducing labor costs.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: a wire end processing device of a wire taking-up machine, comprising a base arranged on the side of a rotating disk of the wire taking-up machine, a clamping mechanism being installed on the base, the clamping mechanism comprising a clamping block being slidably installed on the base and driven by a clamping power device, a wire end clamp addressing device for driving the rotating disk to rotate being installed on the side of the rotating disk, the wire end clamp addressing device drives the rotating disk to stay at the clamping station so that the wire end clamp on the rotating disk is adapted to the position of the clamping block, and a wire end removing mechanism for removing the wire end from the wire end clamp is also installed on the base.

[0005] As a preferred solution, the thread end clamp addressing device includes a friction wheel driven by a rotating power device, the friction wheel frictionally cooperates with the edge of the rotating disk of the wire take-up machine, and a detection sensor for detecting the position of the thread end clamp on the rotating disk is provided on one side of the rotating disk.

[0006] As a preferred solution, the thread clamp addressing device includes a rotating motor for driving a rotating disk of the wire take-up machine, and a detection sensor for detecting the position of the thread clamp on the rotating disk is provided on one side of the rotating disk.

[0007] As a preferred solution, the thread end removing mechanism includes a lever rotatably mounted on the base, the lower end of the lever is defined as a thread removing end, and the lever is driven by a removing rotation power device.

[0008] As a preferred solution, the base includes a fixed support and a device mounting seat installed on the fixed support, the clamping power device is an clamping cylinder, the clamping cylinder is installed on the device mounting seat through an angle adjustment mechanism, the clamping pressure block is fixed on the piston cylinder of the clamping cylinder, and the thread end removal mechanism is installed on the device mounting seat.

[0009] As a preferred solution, the angle adjustment mechanism includes a central hinge shaft and an arc-shaped hole, the arc-shaped hole is arranged on the device mounting seat, the cylinder body of the clamping cylinder is hinged to the center of the arc-shaped hole through the central hinge shaft, an adjusting bolt is arranged in the arc-shaped hole, and the cylinder body of the clamping cylinder is fixed to the device mounting seat through the adjusting bolt.

[0010] As a preferred solution, the device mounting seat is lifted and slidably mounted on the fixed support, and a height adjustment power device is provided between the device mounting seat and the fixed support.

[0011] As a preferred solution, the height adjustment power device includes a vertical bar hole arranged on the fixed support, and the device mounting seat is fixed to the fixed support by bolts constrained in the vertical bar hole.

[0012] As a preferred solution, the height adjustment power device includes a height adjustment cylinder arranged on a fixed support, and a piston rod of the height adjustment cylinder is connected to a device mounting seat.

[0013] After adopting the above technical scheme, the effect of the present invention is as follows: since the thread end processing device includes a base arranged on the side of the rotating disk of the wire take-up machine, a clamping mechanism is installed on the base, and the clamping mechanism includes a clamping block slidably installed on the base and driven by a clamping power device, a thread end clamp addressing device for driving the rotating disk to rotate is installed on the side of the rotating disk, and the thread end clamp addressing device drives the rotating disk to stay at the clamping station so that the thread end clamp on the rotating disk is adapted to the position of the clamping block, and a device for removing the thread end from the thread end clamp is also installed on the base. Therefore, after the wire reel is placed on the rotating disk and the wire is taken up, the rotating disk stops rotating. At this time, the wire clamp addressing device can drive the rotating disk to slowly rotate in the opposite direction, so as to find the wire clamp, so that the wire clamp corresponds to the position of the opening clamp block, and then the opening clamp power device drives the opening clamp block to slide and press toward the tail end of the wire clamp. After the tail end of the wire clamp is pressed down, the head of the wire clamp will open, and then the wire clamp separation mechanism will act to pull the wire out of the wire clamp, so that the wire end is separated from the wire clamp, and the wire reel can be sent out at this time. The current structure of the opening of the wire clamp is to set a spring tongue, and the wire harness can be very conveniently sent into the opening of the wire clamp by the wire clamping and feeding mechanism of the wire take-up machine itself for clamping, but the opening of the wire clamp is still done manually in the prior art, and this solution can replace manual labor and reduce costs.

[0014] Furthermore, since the thread clamp addressing device includes a friction wheel driven by a rotating power device, the friction wheel is frictionally matched with the edge of the rotating disk of the wire take-up machine, and a detection sensor for detecting the position of the thread clamp on the rotating disk is arranged on one side of the rotating disk, the thread clamp addressing device can slowly drive the rotating disk to rotate when the rotating disk stops rotating after the wire disk is fully wound through the rotation of the friction wheel, so that the thread clamp will be driven to rotate to facilitate the detection of the detection sensor, wherein the detection sensor can adopt the current conventional contact sensor or non-contact sensor, wherein the contact sensor only needs to set a contact part on the rotating disk, when the contact part contacts the contact sensor, the rotating disk stops, and the thread clamp corresponds to the position of the opening clamp block. Of course, a conventional non-contact sensor can also be used, for example, a baffle is also set on the rotating disk, and a reflective sensor is set around the rotating disk, when the reflection signal of the reflective sensor is blocked by the baffle, the rotating disk stops, and the position detection of the thread clamp is also very accurate.

[0015] Furthermore, since the thread clamp addressing device includes a rotating motor that drives the rotating disk of the wire take-up machine, a detection sensor for detecting the position of the thread clamp on the rotating disk is provided on one side of the rotating disk. At this time, the power for thread clamp addressing is directly provided by the rotating motor of the rotating disk of the wire take-up machine itself, that is to say, the addressing function of the thread clamp can be integrated into the rotating motor. When the wire take-up machine stops taking up the wire, the rotating motor can slowly rotate to find the position of the thread clamp, thereby realizing the addressing of the thread clamp.

[0016] Furthermore, since the thread end pulling away mechanism includes a lever rotatably mounted on the base, the lower end of the lever is defined as a thread pulling end, and the lever is driven by a pulling away rotating power device, the thread end pulling away mechanism has a simple structure and is easy to implement. When the thread end clamp is found, the lever only needs to be deflected to pull the wire harness out of the clamping mouth of the thread end clamp, and the pulling away action is accurate.

[0017] Furthermore, since the base includes a fixed support and a device mounting seat installed on the fixed support, the clamping power device is an clamping cylinder, the clamping cylinder is installed on the device mounting seat through an angle adjustment mechanism, the clamping pressure block is fixed on the piston cylinder of the clamping cylinder, and the thread head removal mechanism is installed on the device mounting seat. Therefore, the angle of the clamping cylinder can be adjusted through the angle adjustment mechanism, thereby adjusting the angle of the clamping pressure block so that it can be accurately pressed on the tail of the thread head clamp.

[0018] Since the device mounting seat is lifted and slidably installed on the fixed support, a height adjustment power device is arranged between the device mounting seat and the fixed support. In this way, the height of the clamping block can be adjusted by the height adjustment power device, and then the opening angle of the thread end clamp can be better controlled by cooperating with the formation of the clamping cylinder, and it can be better adjusted during assembly.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below through specific examples.

[0026] like Figures 1 to 4 As shown, a wire end processing device of a wire taking-up machine comprises a base 2 arranged on the side of a rotating disk 1 of the wire taking-up machine, a clamping mechanism 4 is installed on the base 2, the clamping mechanism 4 comprises a clamping block 41 slidably installed and driven by a clamping power device 42, a wire end clamp addressing device for driving the rotating disk 1 to rotate is installed on the side of the rotating disk 1, the wire end clamp addressing device drives the rotating disk 1 to stay at the clamping station so that the wire end clamp on the rotating disk 1 is adapted to the position of the clamping block 41, and a wire end removing mechanism 5 for removing the wire end from the wire end clamp is also installed on the base 2.

In order to realize wire taking-up, a wire end clamp is provided on the rotating disk 1, and the wire end clamp is used to clamp the wire end so that the wire harness can be wound around the wire drum. The wire end clamp is a current conventional structure, and the clamping mouth will be opened by pressing the tail of the wire end clamp, and when the tail is released, the wire end will be clamped due to the action of the spring of the wire end clamp itself.

A detection sensor for detecting the position of the thread clamp on the rotating disk 1 is provided on one side of the rotating disk 1. In this way, by adding a new power system to assist in driving the rotation of the rotating disk 1, when the wire take-up machine stops, the rotating disk 1 can rotate so that the detection sensor can detect and ensure that the thread clamp corresponds to the position of the clamp opening block 41.

The detection of the detection sensor can be marked on the rotating disk 1 to facilitate the detection of the detection sensor. The mark can be set according to the type of the detection sensor. For example, if a contact sensor is selected, the mark can be a contact plate, and if a non-contact sensor is selected, a trigger part that matches the sensor can be set on the rotating disk 1. These matching structural designs are conventional structures in the current field of sensor use technology, so the above structures are omitted in the drawings of the specification.

In this embodiment, the pulling rotation power device adopts a rotary cylinder 51, and the lever 52 can be deflected by the rotary cylinder 51, so that the thread end is pulled out of the thread end clamp. Of course, the pulling rotation power device can also adopt a linear cylinder to cooperate with a deflection crank to realize the deflection of the lever 52.

[0033] Among them, the preferred angle adjustment mechanism in this embodiment is a manual adjustment method: the angle adjustment mechanism includes a central hinge shaft 43 and an arc hole 44, the arc hole 44 is arranged on the device mounting seat 22, and the cylinder body of the clamping cylinder is hinged to the center of the arc hole 44 through the central hinge shaft 43, and an adjusting bolt 45 is arranged in the arc hole 44, and the cylinder body of the clamping cylinder is fixed to the device mounting seat 22 through the adjusting bolt 45.

[0034] In addition, the device mounting seat 22 is installed on the fixed support 21 in a lifting and sliding manner, and a height adjustment power device is provided between the device mounting seat 22 and the fixed support 21.

[0035] Also in this embodiment, preferably, the height adjustment power device includes a vertical bar hole 23 provided on the fixed support 21 , and the device mounting seat 22 is fixed to the fixed support 21 by bolts constrained in the vertical bar hole 23 .

[0036] Of course, the height adjustment power device may also adopt other structures, including a height adjustment cylinder arranged on the fixed support 21 , and the piston rod of the height adjustment cylinder is connected to the device mounting seat 22 .

[0037] The cylinder, motor and other actuators mentioned in this embodiment are current conventional technologies. The specific structure, principle and other designs of the cylinder, motor and other transmission mechanisms are disclosed in detail in the "Mechanical Design Manual, Fifth Edition", the 28th printing of the fifth edition in Beijing in April 2008. It belongs to the existing technology and its structure is clear.

[0038] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention.
